| 中文摘要: |
| 为探讨一种新型的特贝钙土壤调理剂（深加工的牡蛎壳粉）对红壤旱地花生产量的影响及其
对土壤酸化的改良效果，通过田间试验，分析了不同施用量（0、750、1 500、2 250 kg/hm2）处理花生产量
和土壤理化性质的变化。结果表明：施用特贝钙土壤调理剂的花生产量可以增加10.2%～23.8%，且成熟
期花生的株高、每株双果数、单果数、总果数和百果重均显著提高。与对照相比，施用特贝钙土壤调理剂
处理土壤碱解氮、有效磷和速效钾分别增加21.65%～118.1%、28.2%～74.1% 和22.6%～47.0%；土壤pH
和交换性钙分别提高0.18～0.33（4.0%～7.3%）和12.9%～18.8%，土壤交换性氢和交换性铝则分别降低
19.6%～62.5% 和34.7%～84.2%。因此，施用特贝钙土壤调理剂是实现红壤旱地花生增产、活化土壤养分和
阻控土壤酸化的重要途径。 |
| 英文摘要: |
| To explore the effects of a kind of new soil conditioner（ named by Tebeigai，made from oyster shell
powder） on peanut yield and soil acidification in red soil，field experiment was conducted，which included four rates of soil conditioner（ 0，750，1 500 and 2 250 kg/hm2），then，peanut yield，yield components，soil chemical
properties were analyzed. The results showed that： the peanut yield in application of soil conditioner increased than
CK（ no soil conditioner） by 10.2%-23.8%， their plant height，grain number and 100-grain weight were improved
significantly. Meanwhile，compared with CK，soil available N，P and K of soil conditioner treatments increased by
21.65%-118.1%，118.1%-74.1% and 22.6%-74.1%；while the soil pH and exchange calcium of soil conditioner
treamnets increased significantly than CK by 0.18-0.33 units（ 4.0%-7.3%） and 12.9%-18.8%，and exchange
hydrogen and aluminum contents reduced than CK by 19.6%-62.5% and 34.7% 84.2%，respectively. Therefore，this
new type of soil conditioner could attain higher yield of peanut in red soil，improve soil available nutrient and reduce
soil acidification. |
